This invention relates to new and useful improvements in a projectingmachine.

One object of the invention is to provide a machine for projecting animage, of any character, and at the same time moving the image bodilyabout the screen, as desired, the machine having been specificallydesigned for moving the image of an aeroplane or other air craft aboutan elevated screen or ceiling so as to simulate the movements of theactual craft in flying.

Another object of the invention is to provide a novel means for mountingand operating the apparatus.

A further object of the invention is to provide a machine of thecharacter described, equipped with means for so mounting the filmtherein as to project a true proportioned image, said film being capableof adjustment in its holder so as to bring it into the correct angularrelation with the screen or ceiling onto which the image is projected.

lVith the above and other objects in view this invention has particularrelation to certain novel features of construction, operation andarrangement of parts, an example of which is given in this specificationand illustrated in the accompanying drawings, where- Figure 1 shows aside elevation of the device, partly in section.

Figure 2 shows a front elevation. Figure 3 shows a sectional view takenon the line 3-3,of Figure 1.

Figure 4 shows a sectional view taken on the line 4-4 of Figure 1, and

Figure 5 shows a plan view of a film whose image is to be projected.

Referring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in each of the figures the numeral1 designates the supporting platform of the machine mounted on which isa supporting framework 2 having vertically aligned bearings in which thevertical shaft 3 is rotatably mounted. The shaft 3 has a screw gear 4fixed thereon which is in mesh with and driven by the worm gear 5 fixedon the transverse shaft 6. One end of the shaft 6 has a spur gear 7fixed thereon which shaft 3 may be slowly rotated.

the housing there is an electric light 14: which is mounted in front oftherefleotor 15, 'sup- 7 from the lightl so as to vary is in mshwith anddrivenby a larger spur H gear 8 which is fixed on the shaftof the motor9. Throughthe mechanism described the The numeral 10 designatesa'substanti'ally enclosed housing, preferably-formed of sheet metal andwhose top is formed withcthe side outlet flues' 11,11, to permit the"escape of hot air fromwithin the housing. The housing 10 is adjustablymounted on a supporting 6' platform 12 so that it may be balanced'on theshaft 3 and said platform is mounted on the upper end of said shaft andis connected thereto by means of a hinge joint 13. Within ported by thebracket 16, all within said housing. This reflector is adjustable towardthe intensity 'Fastened to and distribution of the light.

the front end of the housing, in alignment with the light ll,there isalens telescope 17 having the usual objective lens '17 and between saidlight 14 and telescope 17 and mounted within the housing are thereversely arranged plano-convex condensing lenses 18. The film 19,carrying the image to'b'e projected, is insetted in the suitablebox-like holder 20 in front of the lens 18. This holder has a slidecover 20 foropening and closing the same. m The film 19 may be given anyangle desired,

' relative to the axis of said lenses 17, 18. so that said angle willcorrespond to the angle of said axis with the surface of said screen orceiling and the position of the film in its holder may be varied until acorrect and proportionate image is obtained.

Fastened to the shaft 3 there is a disc 21 formed of fiber or othernon-conducting ma- "9'0 terial whose under side has the concentricarcuate copper strips 22 and wiring 23 is connected to these respectivestrips and forms a circuit through the filament of the light 14.Connected to the wiring, through which the current is supplied to themotor 9, there is the wiring 2t which terminates in the tongues 25, 25,which are carried by the upper end of the framework 2 and are adapted tocontact with the respective strips 22 to complete an electrical circuitfrom the main feed wires to the filament of the light 14:. This circuitis alternatively completed and broken as the disc 21 rotates. It is ofcourse obvious that by making the strips 22 circular the circuit will becontinuous. The hinge 13 is adjustable so that the image may beprojected at any angle desired and the image will be bodily moved abouton the overhead screen describing a circle as the shaft 3 rotates.

What I claim is:

1. A projecting machine including a supporting platform, a frame work onsaid plat form having vertically aligned bearings, a vertical shaftrotably mounted in said bearings, a motor, a train of gears operativelyconnecting the motor with said shaft,a platform hinged to the upper endof said shaft, an inclosed housing adjustable on said last mentionedplatform, means within the housing for projecting an image, said meansincluding an electric light, a disc fastened to said shaft formed ofnonconducting material, strips fastened to said disc, wiring connectedto said strips and forming a circuit through the light, tongues carriedby said frame which contact intermittently with said strips as the shaftrotates, and electrical conductors connected to said tongues.

2. A projecting machine including a supporting frame work, havingvertically aligning bearings, a rotatable shaft mounted in saidbearings, a motor, gearing connecting the motor with said shaft, asupporting platform hinged tothe upper end of said shaft, a housing onsaid platform, and adj ustably connected thereto, an electric lightwithin the housing, a reflector behind the light, a lens telescopefastened tothe front side of the housing, in alignment with said light,reversely arranged plano-convex condensing lenses between said light andtelescope, a box like holder in front of said condensing lenses, a filmin said holder, current conductors forming a circuit through the lightfilament and means carried by the shaft and framework, respectively forcompleting a circuit through said conductors.

In testimony whereof I have signed name.
